' rEUcx. "1"

To all 'whom t may concern Be it known that we, GLENN Hown, EUGENE L. HowE, and RALPH J. TEE'roR, citizens of the United States, residing at Muskegon in the county of Muskegon and State of lWichi an, have invented a new and useful Truc of which the following is a ecification.

he object of our invention is to produce a truck having a readily separable guide wheel and handle forming a ]ack truck, of-

such form that a single guide wheel and handle may be utilized for the transportation of successive trucks, which trucks, when separated from the transportation wheel and handle, will be instable condition; the details of construction being such that ordinary obstructions due to unevenness 1n the surfaces over which transportation takes lace will not interfere with transportation. lrovision is also made whereby the main body of the truck may be readily handled without using 'the jack truck, and -whereby a series of main bodies maybe connected together in a train with a single jack truck for the front one. A further object of our invention is to so construct'and connect the 'parts that a very rigid structure may be produced even b the use of longitudinal slats for the plat orm of the main body.

The accompanying drawings illustrate our invention. Figure 1 is a plan of o ur improved truck; Fig. 2 a side elevation; Fig. 3 a side elevation, in partial vertical section, of the removable jack truck and adjacent body bracket, with the jack truck in supportin and braking position; Fig. a somew at similar. View, .showing the Jack truck separated from the main body bracket; and Fig. 5 a side elevation of a train of our improved trucks.

In the drawings, indicates the main body on'which the load is to be carried, said Vbody being supportedby suitable carrying wheels 11, 11, journaled in a rear truck 12, to which the body 10 is attached. At the middle of the end of body 10, opposite wheels 11, we provide a` single supporting leg 13, which, at its forward face, is p'rovided with an arc-shaped surface 14, thel purpose of which will appear. Extending forwardly vfrom leg 13 near its upper end is 55 `out, top and bottom, as indicated at 17, 17.

an arm which is provided near its end with an eye 16 which is preferably rounded projecting 'y perforation 1.6

.a rearwardly projecting arm having a transverse depression '51 adapted to receive the horizontal arm of a transversely arranged angle iron 52, said horizontal arm rearwardly from the vertical arm. The angle iron 52 is attached to arm 50 by means o bolts 53 which may also pass through the platform, or platform bar, 10,v

other bolts 54 being also provided for attachlng the arm 50 to the platform, or platform bar, l10. Otherl bolts 55 pass through the horizontal arm of angle iron 52 and through other platform bars 10. It is de cidedly advantageous to have the rear truck 12 a single solid substantial structure, so

that, when connected to the angle bar 52, by

bars 10, duced;.

The jack truck which is designed to cooperate with the structure thus far described, comprises a main bifurcated body 21 between the legs of which is journaled a caster wheel 22. Body 21 is provided with a socket 23 which receives a handle `bar 24. At .its top is an upwardly and forwardly projecting pin 25'which is circular in horia rigid/substantial truck-is prof zontal section at its middle and uniformly flared outwardly at its base so as to fit, with a slight play,

the lower end of the perforation 16, the arrangement being such that the finger 25 may be hooked upwardly into the and-the wheel 22, if desired,- thrown back l face 14 of leg 13, the leg end of the main truck being raised, to the positions shown in f Figs. 2 and 3, as the wheel 22 passes be, neath the arm` 15.

The cross bar 24 of the handle bar 24.- lies considerably above arm 15 preferably, and consequently, when either a push or pullis exerted upon this cross bar, under normal conditions, the -line of action will be above the pin 25 if it be a push and vbelow the pin if it be a pull, so that in either' case, any force acting to transport the structure will first draw wheel 22 away from face 14 so as to eliminate the braking action. As soon, however, as the handle bar is dropped, its weight will serve to drive wheel 22 back against face 14 `Vand thus automatically 4brake the structure against movement.

The jack truck may be readily withdrawn by an upward swinging of the handle bar and a Asubsequent forward movement of the into frictional contact with bracket 58 should that any vwheel 22, as indicated in Fig. 4, the leg 13 being thus lowered to the Hoor where it will support the load-carrying -body in a xed position.

We deem it especially important that the I yleg 13 is arranged immediately to the rear of the wheel 22, because, in using the structure on uneven surfaces, the lower end of the leg is so close. to the jack truck wheel obstructions which' will be passed over by this wheel will be of such character as to be alsol passed-.over by the leg and, of course, any obstructions which are-notengaged by the jack truck wheel, will also be avoided by the leg. In order to facilitate the handling of the main truck readily when empty, we have found it convenient to provide leg 13 with an upwardly and forwardly extending arm 56, providedwith aforwardly extending handle 57 at its upper end. We also find it very desirable to provide each main truck, at its rear end, with a rearwardly extending bracket 58, provided at its "end with an upwardly extending pin 59, adapted to receive any one of the eyes 16 so that several of the main trucks may be connected together, as shown in Fig. 5.-. The preferably be so formed as to require slight elevation of the front end of the truck, beyond what is required when coacting with the jack truck, in order that the leg 13 may be lifted far enough from the floor to insure passage over possible obstructions.

Arm 15 is projected forwardly far enough in front of the end of the load-carrying platform so that the jack truck may be brought into association with said arm at any position through an angle of considerably more than 180 swing around a vertical axis. By

ranged end to end in very close sequence, and yet be readily withdrawable from the row by the use of a jack truck, said jack truck being easily run into place, with handle 24 lying substantially at right angles to the general line of the truck and brought into correlation with the eye 17 of the desired truck.
